CLEAR-VISION SIQIDING SHIELD.

Application filed March 26, 1926. Serial No. 18,387.

This invention relates to Windshields. It is the object of the present invention to provide a windshield of the singl -pan e1, vertical sliding type which will present absolutely no obstruction to the vision,

One of the chief objections to the double panel shield is the rubber strip that is ordinarily used between the meeting edges of a two-panel shield. Such a strip is shown and described in detail in the McCormick Patent No. 1,259,117.

A single panel, vertical sliding, clear vision shield of this type is described and claimed in the prior Simpson application Serial No. 686,716. This shield has gone into very extensive use, but it is not an absolutely clear vision shield when the same is raised; for like all Windshields, and all windows used in automobiles, it does have a window sash channel for seating the same on the sill, consequently when the shield is raised for the purpose of getting direct ventilation, the sash bar interferes with the line of vision;

this will be-more fully explained herein-' after.

Furthermore, in this. new type ofventilating windshield, which is known as Fisher V ,V type, it has been found a very diflicult thing to get an absolutely water-tight seal around the sill.

It is the object of the present invention to effect two special results; one is to eliminate the obstruction to the vision when the shield is raised, the other to secure, as near as may be, a water-tight seal at the sill.

In the drawings:

Fig. 4 is a fragmentary 'elevationalview of the shield adjacent toone corner of the frame. This is an enlarged view looking toward the shield from the front of the car; the panel is partly raised. Flg. 5 is a section on the line 5 5 of Fig. 4.

Fig. 7 is a vertical section, fragmentary in character, through the forward part of the car, showing the driver in position and indicating how the shield would interfere with the line of vision in case it had the usual lower sash channel.

As explained in the prior Simpson application, the sill a of the windshield has a trough b fitted across the entire length of the. sill, this trough is bent to direct an air current entering the mouth 0 of the trough, down behind and forward of the instru-, ment board at of the car. This serves as a foot ventilator and entirely eliminates the necessity of the usual cowl ventilator which will be seen on most cars; it will be noted that no such ventilator is shown in Fig. 1. The mouth of this ventilating draft is controlled by raising and lowering the single which may be raised and lowered by a regulator 7 controlled by a detailsof this regulator are not here shown as they are described in the prior Simpson application, and also in the Simpson application Serial No. 702,753.

The first inch or so of the rise in the panel serves to control the, amount of air which is delivered through the ventilating trough, and forward of the instrument board. The panel may be raised stilLfurther, about 3 or 4 inches, by reason of the pocket It in the This gives a direct draft into, the car. This window regulator is controlled by the "usual clutch, after the manner of all window regulators, consequently the panel stays locked in any position to which it has channel which is employed on all windshieldpanels, on .the lower edge,- on the sill. invention to when they seat It is the object of the present completely eliminate this chan-' edge, and at the same time effect a very tight water seal. 1

To this end, the sill is grooved and in this 5 groove is located a relatively heavy strip nel and afford a sliding panel with a free of metal designated and which is preferably an extruded soft metal strip,-aluminum or aluminum alloy. This can be easily bent and shaped to the curvature of the sill from side to side as it appears in Fig. 1.

This extruded metal strip is provided with a dovetail socket in its upper face, In this socket is secured the rubber sill strip m. This sill strip m is constructed of moulded extruded rubber and preferably has a pair of hollows g which serve to make it easily deformable; an extension of this rubber strip on the inside runs over the dovetail on the inside and seats on the top of the metal strip. There projects forwardly from this portion of the rubber, a weather fin 0; this is intended to just about meet the glass; in some cases it may wipe the glass slightly and in others it may have a slight clearance from the glass. It is impossble in the assembly work to work to such dimensions as to insure an absolutely certain position of this fin at all times. However, it is the ob'ect of this fin to substantially seal the glass above the main portion of the strip from water that may be blown through where the glass rests on the cushion portion of the strip.

It will be seen from this description that the purpose of this rubber strip is two-fold; one is to form a springy soft cushion to receive the unframed edge of the glass, and enable the builder to do away with the universally resent sash channel. The hollow rubber will serve as an ample protection for the bottom edge of the glass, especially is this true in view of the window regulator with a lock such as described in the Simpson- Schmidt- Carstons Patent No. 1,343,410, which looks the window against either raising or falling. It will be apparent therefore, that when the panel has been turned down firmly on the rubber cushion it will be locked in this position by the regulator and the panel cannot jump up and chatter on the sill with the vibrations of the car. This therefore serves for as good a protection for the bottom of the glass as a sash channel, and when the panel is raised to the upper position b of Fig. 7, there is no opaque member in the line of vision to interfere with driving.

Now as to some of the other details, it will be seen that the weather fin 0 can be turned up at the corners as shown in Fig. 3, also Figs. 4 to 6 inclusive. The clip which is nailed to' the offset 8, which seats the lower end of the moulding serves to turn back the fin of thisrubber strip and causes the same to turn up between the rubber window guide a which'is preferably felt, velvet lined, as at '0. This serves to erect at the corner and around the joint with the window guide such a barrier as is calcu lated to exclude the weather driving in at the corners. This has been the most critical point of this new type of windshield.

It is preferable to also use a vertical angle strip of rubber, designated as, and held in place by the metal plate y secured to the side of the window post with the screws 2. This forms an additional weather seal for the corner. 1

3. In "windshield construction, the combination of a windshield frame provided with a sill, a single panel operating in said frame, a strip supported on the sill and of a soft distortable material, the said panel having a lower free edge adapted to be received on the said rubber cushion, panel is in position to close the opening in the windshield frame, and a window regulator for operating said panel and locking same in various positions of adjustment.
